your left hand needs not to be too tired and not to be understimulated during your practice. If you use your right hand to play whole pieces or long sections HS your left hand will not work enough and if you use your left hand to play whole pieces, long sections or left hand studies your left hand will be too tired.
If you alternate left hand and right hand in your HS practice making sure that no hand becomes too tired you should give to both the right amount of practice.
Since your scale is not mastered HT because of your left hand problems you should practice it HS, the first times you will notice that your playing is sloppy and that you miss the target of your fourth finger, but when your left hand begins to tire switch to right hand and let your left hand rest in your lap. When your right hand begins to tire switch to left hand and let your right hand rest on your lap. As you keep alternating hand you will see that the resistance, accuracy and movements of your left hands are improving in a matter of minutes.

As for practicing descending scales I would divide the scale in chunks so that you stop before passing a thumb passage.

i.e  g major descending scale LH

G    F#  E 
                           FIRST CHUNK
1    2     3


D   C   B   A
                           SECOND CHUNK
1    2   3   4


G    F#  E 
                           THIRD CHUNK
1    2     3


D   C   B   A  G
                            FOURTH CHUNK
1    2   3   4  5


Hope this helps
Good luck and let us know

Mind you, I suggested you to change the way your practice because your problem with the left hand fourth finger doesn't sound like something being caused by an hand injury. If it was tendonitis or CTS you would feel your fifth finger as weak as the fourth. It sounded like the typical understimulated left hand and overstimulated right hand problem. But only you can know whether what you feel is a physical problem caused by injury or just a technique problem.

thx all. 
First of all, I dun think its kind of injury.  I think I ignore my left hand's playing for long time is the main point why my left hand's fourth finger become so handicap.  Honestly, my left hand is born to be a bit weak compare to other people.  And I always concern my right hand's playing more than my left in the past.  But when I'm getting older, I found the problem is getting more serious.  And I do need some useful practise or study to stimulate my left hand esp.  fourth finger.  I feel so shameful to have such handicap fourth finger which really make me don't want to touch the piano sometimes.
